About Me

I am a board-certified gastroenterologist with a special interest and expertise in therapeutic endoscopy and specialized nutrition support for cancer patients. Using advanced endoscopic techniques I can access the length of the gastrointestinal tract to diagnose, treat, and palliate cancers that develop there.

To diagnose and treat cancers I use procedures including colonoscopy, upper gastrointestinal endoscopy, small intestinal enteroscopy, endoscopic ultrasound (EUS), fine-needle aspiration, endoscopic retrograde cholangiopancreatography (ERCP), and capsule endoscopy (in which patients swallow a capsule containing a miniature wireless camera). These procedures enable me to obtain images of the GI tract and tissue samples for biopsy. In some patients I can ablate, or destroy, intraluminal tumors and polyps using a variety of endoscopic techniques.

To provide patients relief from intestinal blockages I perform endoscopic procedures to insert stents and drainage tubes, which allow the GI tract to resume functioning.

During treatment, cancer patients may develop gastrointestinal tract failure and may require nutrition support, which I can provide using total parenteral nutrition (TPN) and feeding tubes.

My research involves developing and testing novel endoscopic techniques. In one area of research I am developing new ways to access the biliary tract to place internal drains for patients with jaundice. I am also developing techniques to remove large colonic polyps and precancerous lesions in the esophagus and stomach so that patients with these problems can avoid major surgery.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time. Currently, clinical trials focused on the conditions I treat are enrolling new patients.
